Phạm vi áp dụng / Scope of standard

This practice covers the requirements for the apparatus and
equipment used to prepare specimens for the determination of length
change in hardened cement paste, mortar, and concrete; the
apparatus and equipment used for the determination of these length
changes; and the procedures for its use.

 Methods for the preparation and curing of test specimens,
conditions of testing and curing, and detailed procedures for
calculating and reporting test results are contained in applicable
test methods.

The values stated in either SI units or inch-pound units are to
be regarded separately as the standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in nonconformance with the standard.

Values in SI units shall be obtained by measurement in SI units
or by appropriate conversion, using the Rules for Conversion and
Rounding given in IEEE/ASTM SI 10, of measurements made in other
units.
